They don't look like they're from the same litter...could the large one be from last year's litter? The faces seem to me to have a different maturity appearance...I thought initially they were mother and kits, but there isn't enough size difference. So...maybe a different litter?

I'm the one who sent you a link of the bobcat photos I made up on Mt. Tam earlier this year. http://www.flickr.com/photos/trishcarney/sets/72157603977441338/

If it is not asking too much may I ask the general area of Marin of these sightings. I am not asking exact location but general area. I would love to hike in the general area in hopes to see bobcat kittens. I have seen lots of bobcats but never kittens. If I got to see bobcat kittens with my own eyes in the wild I would be the happiest camper out there!!

Thank you for considering!

Keep up the grreat work. Really appreciate seeing your images especially since I live in Marin and one who really wants to celebrate the local wild in our midst!
